Hi, I need to replace the bearings on my cabriolet trailing arms, I like the set up shown here,https://www.fiatforum.com/punto-mk1-guides/179035-rear-suspension-arm-repair-kit.html.
Has anyone done similar? I'm thinking about 2.5mm bore for the grease gallery. I did a Pugeot 305 van yrs ago and used expanding foam to fill the void in the arm and drilled the centre between the bearings to fit a grease nipple. Drilling the bolts looks very professional. Thoughts please,

Drilled grease ways in the pivot bolts and fitted nipples. Will take the arm apart before I drill the bushing so I can see what's the best approach.
